ICD-10 Code A06.0 – Acute amebic dysentery (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A06.0 – Acute amebic dysentery
What it is
A06.0 identifies an acute intestinal infection caused by Entamoeba histolytica, producing dysentery. Use it when the record documents acute amebic dysentery, not a nonspecific diarrheal illness.
Clinical signs
Typical findings include frequent loose stools with blood or mucus, abdominal pain, and tenesmus. Clinical features vary; refer to documentation for confirmed amebic infection.
When to use this code
Use this code when the provider documents acute amebic dysentery or acute intestinal amebiasis with dysenteric symptoms. It may also fit when stool or other testing supports Entamoeba histolytica and the diagnosis is clearly stated. Check documentation if the chart only says infectious diarrhea or colitis.
Do not use for
Do not use A06.0 for asymptomatic intestinal infection, extraintestinal amebiasis, or unspecified diarrhea. If the note does not confirm acute dysentery, choose the more precise documented diagnosis.
Coding tip
Capture the provider’s exact wording and avoid assigning A06.0 from symptoms alone.
